Thank you Armin, Please educate me a bit, cause I am a bit perplexed by your mail.
You say OJB does not work well w/ JDO, use ODMG or PB

OK, I understand that.
then you say:

If you want to use JDO, please have a look at JPOX or Speedo (or other

JPOX is a implementation of JDO, isn't it? So can I use OJB w/ JPOX then?
Or should I just use JPOX ? (this indicates my confusion at what exactly OJB does on the top of JDO). Please help me out.
Hi Dmitry,

We cannot use OJB w/ JPOX. Basically, the JDO support in OJB works only with Sun JDO 1.0.1 [1]. If you want to stay in "Apache home", you should try Apache JDO wich is working on a final release of a "JDO 2" version.

Antonio Gallardo.

Hi Dmitry,

I don't know what's going wrong when running the tutorial (seems that Product.class was correctly enhanced by the JDO enhancer). But I wouldn't recommend OJB's JDO 1.0-api implementation for production environments.
The PB-api and ODMG-api are stable and ready for production use

If you want to use JDO, please have a look at JPOX or Speedo (or other projects)

Hi, I am developing a java application and I am considering OJB technology to store objects' states seamlessly in the PostgreSQL database. In short I am failing to get tutorial5 up and running. I followed instructions on this link:
